DRAFT-BAR FOR HARROWS.

Specification of Letters Patent.

Patented Mar. 15, 191.0.

Application filed January 16, 1909. Serial No. 472,707.

To aZZ whom it may concern:

Be it known that I, STEPHEN A. D. Mo- Govnnn, a citizen of the UnitedStates, and a resident of Oneida, in the county of Knox and State ofIllinois, have invented certain new and useful Improvements in Draft-Bars for Hal-rows, of which the following is a specification.

My invention relates primarily to means for separably connecting theseveral sections of the drag-bar of a multiple harrow, and to the meanswhereby the draft animals may be attached to any number of saidsections.

The objects of the invention are to provide a simple, strong, economickeeper or connection which may be quickly and easily applied to theabutting ends of two of the harrow sections to secure them rigidlytogether, and which may as readily be removed therefrom to disengagethem; and further, to provide improved means whereby either section, orany preferred number thereof may be drawn by the same draft mechanism orparts thereof, whether for passing through gates, through narrow lanes,over bridges, for local transportation, or for operation in a field.

. To the end of accomplishing these objects the invention consists inconstructions and combinations hereinafter described.

In the accompanying drawings, which illustrate a preferred embodiment ofmy invention: Figure 1 illustrates a selective draft mechanism; Fig. 2,a plan, illust ating, when taken in connection with Fig. 1, a mode notonly of the means of attachment, but further, the means of securementtogether of the harrow draft-bar sections; Fig. 3, a detail, showing oneof the central rods comprising the four way hitching means; Fig. 4, amodification, showing how the central rods may be applied to a twosection harrow; Fig. 5, a similar view, show ing how the same rods areattachable to a single harrow section; Fig. 6, a vertical, centralsectional elevation, taken in the line 5-5 in Fig. 4; Fig. 7, a detailof one of the hook members shown in plan view throughout the principalfigures; and Fig. 8, a detail, showing a modified construction thereof,or of the rear end connection of the means of attachment to therespective harrow sections.

Referring to the drawings, 2, 2, 2, 2 represent individual sections ofthe drag-bar of a toothed harrow which may be of any ordinaryconstruction. Suitable means of attachment thereto, 3, which may also beof any preferred construction, are also shown- (see Figs. 1, 2, 3, 4 andConnecting the proximal ends of each pair of harrow sections is atubular keeper 4, preferably of rectangular form in its crosssection.The keepers are adapted to fit snugly over the abutting ends of thesections, and each is provided wit-h apertures 5, through which pins (5,shown best at Fig. 6) may be passed to interlock with selectiveapertures in the ends of said sections. 'lransversely through therespective sect-ions 2 are passed eye-bolts 14, the eye of each of whichis forward of the section to which it is attached. To these eyes areattachable by hooks 8 flexibly connected by a link or links 9, rods 10,each of the outer pair of which has at its forward end a hook 16 adaptedfor engagement with a ring 11, and the inner pair of which rods, beingelongated, are adapted to engage a main ring 12. Intermediate each pairof rings 11 and 12 is a flexible connection comprising a rod 17, links18 and a hook 1S).

WVhen it is necessary to pass through a very narrow space, the meansshown at Fig. 5, comprising the elongated rods 10, links 9 and hooks 8are engaged with a single harrow-section, the keeper 4 having beenremoved therefrom. Two sections may be drawn by the means shown at Fig.4, in which one of the keepers is employed to rigidly secure thesections in alinement by the act of dropping one of the pins througheach of the apertures in the keeper and in the proximal ends of thesections, (selective spacing being effected in an evident manner) thesame draft means being employed as shown at Fig. 5, but the eye-bolts 14positioned elsewhere in the draft bars from what is there shown. If itbe desired to draw three sections (see Fig. 1 in connection with Fig.2,) the outer links 9 are engaged with the eye-bolts in the outersections 2, preferably by means of an interposed link and a double hook8, see Fig. 8, and the elongated rods 10 are engaged with the centralsection in the manner shown at Fig. 5. Four sections may be united asshown at Fig. 2 and drawn by the means shown at Fig. 1. Any of thehooks, it will be apparent, may be instantly engaged or disengaged, andthere will be no necessity of carrying even a single tool, as no boltsor nuts are to be applied or removed in assembling or disassembling theseveral sectlons.

It Wlll be manifest and 1s well known to those W110 are skilled in theart of agriculture, that when it is desirable to pass through rgates,when it is necessary to cross bridges or when it is required to locallytransport a sectional harrow, my improvements will be found to be notonly desirable but essential. Furthermore, it will be clear that a rigidconnection is furnished by the keepers 4-, whereby, when draft isapplied to either end of the multiple draft or drag-bar the latter willnot flex but each sect-ion thereof will be drawn in a line with relationto the other sections thereof. The drag bars are, by means of the hooks,readily detachable, and a single section or any number thereof may,

virtually, instantly and selectively be em ployed.

Having thus described my invention, I claim as new and as saidinvention:

1. A draft-bar for harrows comprising a plurality of sections, a tubularkeeper provided with a series of apertures, inclosing and uniting theabutting ends of said sections, )ins adapted for engagement withselective ones of said apertures, whereby said sections may be lineallyspaced, eye-bolts fixed transversely of each section, hooks removablyengaged therewith, a main draftring, and selective means interposedbetween said ring and hooks whereby a predetermined number of sectionsmay be drawn by means of said ring.

2. A draft-bar for harrows comprising a plurality of sections, means forlineally uniting their proximal portions, an eye-bolt fixed transverselyof each of said sections, a main draft-ring, intermediate draft-rodshaving each a hooked end adapted to engage said ring, links secured tothe other end of said rods and removably engaged with said eyebolts,outer rods in pairs having each a hooked end, a ring flexibly connectingthe proximal ends of said outer rods, a flexible connection at the outerends of each of said outer rods, and means for releasably engaging saidconnections with the main draftring.

In witness that I claim the foregoing as my invention, I heretosubscribe my name in presence of two witnesses.
